I bought a pair of leggings from them, ordered on a Weds afternoon, and because I wanted to wear them on the Friday I paid for next day delivery. I kinda forogt about them so by Friday I was just annoyed that they hadn't arrived. I emailed them and sent them a message through the form on the website and hadn't recieved a reply by the Tuesday, and they don't have a phone number on their website due to their "excellent online customer service" HA!
I contacted them via Twitter, all the responses were quick but they basically just said it had been collected by the courier, and they then didn't know where the item was by the Thursday. Finally they found out that there wasn't a postcode on the package, which wasn't my fault because there's no way I could have put the order through without one.
Anyway, got it on the Monday, so 11 days after I was meant to recieve it, and I had to push them to refund the £6 or whatever it is that I paid for next day delivery. I was fuuuuuurious!!
